Hi to everyone,
Few month ago I have developed a web application (using hibernate) that is currently running on an Oracle Application Server 10g without any problems...
Now I have to make this application executable on a Oracle9iAS Containers for J2EE 1.0.2.2 using Java 1.3.1.
In order to do this I have recompiled the hibernate3.jar with a 1.4 jdk setting the target="1.3" and that worked fine.
After this I have included this library in my application and re-compiled everything with JDK 1.3.1 obtaining a .WAR package.
The problem arise after the deploy, when a page reaches the instruction below:

// Init Hibernate
if (sessionFactory == null)
sessionFactory = new Configuration()
.configure(conf.getProperty(PARAM_HIBERNATE_CONFIG_FILE))
.buildSessionFactory();

This instruction refers to the hibernate.cfg.xml file listed below:

<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.aggressive_release">true</property>
<property name="hibernate.cache.use_second_level_cache">false</property>
<property name="connection.datasource">jdbc/GE_Loaders</property>

<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>
<property name="hibernate.jdbc.batch_size">30</property>


<!-- Echo all executed SQL to stdout -->
<property name="show_sql">false</property>

<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.Oracle9Dialect</property>

<!-- Mapping files -->
<mapping resource="DMGE_Loaders/model/adeguamento/Adeguamento.hbm.xml"/>
<mapping resource="DMGE_Loaders/model/pesiAnnoCCF/PesiAnnoCCF.hbm.xml"/>
<mapping resource="DMGE_Loaders/model/pesiAnnoMeseCCF/PesiAnnoMeseCCF.hbm.xml"/>
<mapping resource="DMGE_Loaders/model/pesiGestionale/PesiGestionale.hbm.xml"/>
<mapping resource="DMGE_Loaders/model/cambiValuta/CambiValuta.hbm.xml"/>
</session-factory>
</hibernate-configuration>

This works perfectly under Oracle AS 10g but now on the 9i AS when calling that instruction it gives back what follows:

It seems a usual ClassNotFoundException but I don't use any class called Event!
Any idea?
Thanks in advance

Somehow you are loading the mapping file events/Event.hbm.xml



This file may reference the event class.
Perhaps you are using differenthibernate.cfg.xml as you thought ?

Hi,
I'm sure I'm not using a different xml file because I have buildt the WAR package using Netbeans as IDE and including exactly that xml file.
What it's strange to me is that my application works well on tha Application Server Oracle 10g but not in the 9i one. Maybe is still not compiant the re-compiled hibernate.jar library?
Has no one experienced this phenomenon?
Should I use another hibernate version, an older one for example?
Thanks bye
Paolo
